If you don't mind that all 20 boxes have the same software installed;
1) Use one box or jail as the build box. Only this box/jail needs a ports
tree. The others don't need /usr/ports, nor /var/db/ports or /var/db/pk=
g.
2a) In case of real boxes, rsync /usr/local from the build box to the other
boxes. Then re-start updated ports. =20
2b) In case of jails, have all but the build jail share (a read-only)
/usr/local via nullfs. Use rsync to copy /usr/local from the build jail=
to
the shared location of the other jails, then restart the upgraded ports=
on
all jails.
Except from /usr/local, you might need to update stuff in other parts of the
filesystem, depending on the port. Like /etc/rc.conf, or sometimes stuff in
/var.=20
The usage of nullfs (with unionfs) is described on one of my web pages:
http://www.xs4all.nl/~rsmith/unix/misc.html
Look under the section "Using nullfs and unionfs for the ports tree in a ja=
il".
Hope this helps.
